Economic optimization and sensitivity analysis of photovoltaic system in residential buildings

This paper deals with the problem of optimal size of grid-connected photovoltaic (PV) system for residential application. It is assumed the PV system can input or output liberally the electricity to the utility electricity grid. A simple linear programming model is developed. The objective is to minimize the annual energy cost of a given customer, including PV investment cost, maintenance cost, utility electricity cost, subtracting the revenue from selling the excess electricity. The model reports the optimal PV capacity that customers adopt with their electricity requirements. Using this model, an investigation is conducted of economically optimal PV investment under several conditions for a typical residential building. Additionally, the sensitivity of levelized cost and simple payback period to various economic and technical circumstances has been analyzed.

Optimization of transesterification conditions for the production of fatty acid methyl ester (FAME) from Chinese tallow kernel oil with surfactant-coated lipase

Surfactant-coated lipase was used as a catalyst in preparing fatty acid methyl ester (FAME) from Chinese tallow kernel oil from Sapium sebiferum (L.) Roxb. syn. Triadica sebifera (L.) small. FAME transesterification was analyzed using response surface methodology to find out the effect of the process variables on the esterification rate and to establish prediction models. Reaction temperature and time were found to be the main factors affecting the esterification rate with the presence of surfactant-coated lipase. Developed prediction models satisfactorily described the esterification rate as a function of reaction temperature, time, dosage of surfactant-coated lipase, ratio of methanol to oil, and water content. The FAME mainly contained fatty acid esters of C16:0, C18:0, C18:1, C18:2, and C18:3, determined by a gas chromatograph. The optimal esterification rate was 93.86%. The optimal conditions for the above esterification ratio were found to be a reaction time of 9.2 h, a reaction temperature of 49 °C, dosage of surfactant-coated lipase of 18.5%, a ratio of methanol to oil of 3:1, and water content of 15.6%. Thus, by using the central composite design, it is possible to determine accurate values of the transesterification parameters where maximum production of FAME occurs using the surfactant-coated lipase as a transesterification catalyst.

对焦化剩余氨水采用混凝-微滤法进行处理,研究了以聚合氯化铝（PAC）为混凝剂、聚丙烯酰胺（PAM）为助凝剂的混凝-微滤法的最佳工艺条件。实验结果表明：该法在最佳工艺条件处理剩余氨水时,浊度、色度去除率分别达96%、86%。采用混凝-微滤法处理焦化剩余氨水的效率高于单独采用化学混凝法时的处理效率。     

煤气质量对甲醇生产的影响及解决措施

由于煤气质量不能满足甲醇生产的要求，我公司焦炉煤气制甲醇装置投产后，甲醇生产不稳定。通过技术改造，增加了电捕焦油器、低温水洗、栲胶脱硫、焦炭过滤器等煤气处理方式，提高了煤气质量，满足了甲醇生产的要求。     

系列新型双级注水泥器的设计与应用

针对常规双级注水泥器现场应用时可能会出现打开困难、关闭不严或关闭困难、钻除附件后密封失效等问题,开发了系列新型双级注水泥器。该注水泥器采用内关闭式结构,减少了运动部件,打开和关闭均由相同材质的零件相对运动实现,从而避免了因温度、压力等因素造成的配合间隙变小而不能正常打开/关闭的问题;在关闭套和本体间设置了防转机构,以便在附件钻除过程中,有效防止关闭套与钻头一起转动而引起的密封失效。介绍了系列新型双级注水泥器的结构、工作原理和技术特点。地面试验和现场应用证明,系列新型双级注水泥器达到了设计要求,解决了常规双级注水泥器现场应用时常出现的一些问题。     

烧结温度对莫来石刚玉复相材料微观结构的影响

以铝型材厂阳极氧化废渣和粘土为主要原料研制莫来石刚玉复相材料，探讨不同烧结温度对复相材料的影响，分别采用XRD和SEM表征样品的晶相结构和显微结构。结果表明烧结温度可显著改变样品中晶相的组成和各晶相的相对含量；各样品主要存在莫来石固溶体相和刚玉相两种结晶相，其中莫来石固溶体为主晶相，在不同温度下有两种组成（Al4.544Sil．456O9.728和Al4.59Si1.41O9.70）：随烧结温度的升高，莫来石含量逐渐增多，至1650℃，试样中莫来石含量为100％。扫描电镜下莫来石呈针柱状交织，晶体发育良好，预示得到的材料具有良好的宏观力学性能。
